GraphQL Inspector is a set of tools to help you better maintain and improve GraphQL API as well as GraphQL consumers.

GraphQL Inspector outputs a list of changes between two GraphQL schemas. Every change is precisely explained and marked as breaking, non-breaking or dangerous. It will help you validate documents and fragments against a schema and even find similar or duplicated types.


  • Validate schema
  • Schema change notifications on Slack, Discord or Webhook
  • Finds breaking or dangerous changes
  • Validates documents against a schema
  • Finds similar / duplicated types
  • Schema coverage based on documents
  • Serves a GraphQL server with faked data and GraphQL Playground
  • Github Application
  • Github Actions

GraphQL Inspector has a CLI and also a programatic API, so you can use it however you want to and even build tools on top of it.
